This paper develops a new framework and statistical tools to analyze stock returns using high-frequency data. We consider a continuous-time multifactor model via a continuous-time multivariate regression model incorporating realistic empirical features, such as persistent stochastic volatilities...

This paper focuses on revisiting an old issue by advanced econometrics analysis: the risks in the U.S. stock market. We analyze the firm's exposure to exchange rate, interest rate, and market shocks by the pooled regression with the error cross-section dependency. We not only examine the...

This paper builds up a simple New Keynesian model and revisits the relationship between unemployment and in ation in the long-run. It finds that when the labor market is affected by downward nominal wage rigidity, this relationship goes beyond the tradeoff between the first moments of...

We investigate the effect of uncertainty on investment. We employ a unique dataset of 25000 Greek firms' balance sheets for 14 years covering the period before and after the eurozone crisis. A dynamic factor model is employed to proxy uncertainty. The investment performance of 14 sectors is...
